Carotid endarterectomy: A carotid endarterectomy is a minimally invasive procedure to remove plaque from within your carotid artery, the main blood vessel that carries blood to your brain.
An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [1] [2]The material consists of mostly macrophage cells, [3] [4] or debris, containing lipids, calcium and a variable amount of fibrous connective tissue.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
The fibro-lipid (fibro-fatty) plaque is characterized by an accumulation of lipid-laden cells underneath the intima of the arteries, typically without narrowing the lumen due to compensatory expansion of the bounding muscular layer of the artery wall. Beneath the endothelium, there is a "fibrous cap" covering the atheromatous "core" of the plaque.
Also arterial hyalinosis and arteriolar hyalinosis refers to thickening of the walls of arterioles by the deposits that appear as homogeneous pink hyaline material in routine staining. [3] It is a type of arteriolosclerosis, which refers to thickening of the arteriolar wall and is part of the aging process.
Arterial stiffness occurs as a consequence of biological aging, arteriosclerosis and genetic disorders, such as Marfan, Williams, and Ehlers-Danlos syndromes. [1] Inflammation plays a major role in arteriosclerosis and arterial stiffness. [ 2 ]
Peripheral artery disease – occurs when atheromatous plaques build up in the arteries that supply blood to the arms and legs, causing the arteries to narrow or become blocked. [ 1 ] Erythromelalgia - a rare peripheral vascular disease with symptoms that include burning pain, increased temperature, erythema and swelling that generally affect ...
